Register 7: GPIO Raw Interrupt Status (GPIORIS), offset 0x414
The GPIORIS register is the raw interrupt status register. Bits read High in GPIORIS reflect the
status of interrupt trigger conditions detected (raw, prior to masking), indicating that all the
requirements have been met, before they are finally allowed to trigger by the GPIO Interrupt
Mask (GPIOIM) register (see page 110). Bits read as zero indicate that corresponding input pins
have not initiated an interrupt. All bits are cleared by a reset.

Preliminary
Description
Reserved bits return an indeterminate value, and should never
be changed.
GPIO Interrupt Raw Status
Reflect the status of interrupt trigger condition detection on pins
(raw, prior to masking).
0: Corresponding pin interrupt requirements not met.
